301: Zdeněk Rosa of Bohemia Hop Is Bullish on the Future of Czech Hops
Craft Beer & Brewing Magazine Podcast
The Importance of Draft Resistance in Hops
Bohemial Hops is trying to breed later varieties that can overcome the summer heat and then do well later on. The danger for science is that being in a laboratory, it started so far from flowering quite early,. And if the tropical temperatures come at that time, they can actually, the flowers can dry down and then you have less yields, less cones. We've got now new line varieties which are close to size, which are called Satchine's or Hans Kohnfort.
When brewers think of Czech hops, they naturally think of Saaz, whose delicate and ethereal character is nearly synonmyous with lager itself. Yet while craft brewers around the world have developed an obsession with punchy New World hops and the character of specific varieties, they often know relatively litle about the hops from this region that’s been growing them for more than a millennium.
In this episode, we sit down in Žatec—the home of Saaz—with Zdeněk Rosa, chairman of Bohemia Hop, the collective of all Bohemian hop growers. Here, Rosa digs into:
- the promising overall trajectory of Saaz growth in recent years, despite the disastrous harvest of 2022
- how agronomy and growing operations differ in Bohemia compared to the Pacific Northwest
- the unlikely specifics of how weather impacted the 2022 harvest
- the development of other varieties that offer similar character to Saaz but with better yield and sustainability
- newer, more expressive Czech aroma varieties such as Saaz Shine and Saaz Comfort, which offer enticing possibilities for lager and other kinds of beer
- leaning into a Czech take on cold IPA using more characterful Czech aroma hops
And more.
